Abstract

Bamboo plants in Indonesia are familiar plants and have not been utilized optimally. Most people only use the stems for daily needs and a small part for industry, while the leaves are left as waste. Bamboo leaves have a fairly high silica content. Bamboo leaves that have fallen and are scattered on the ground (bamboo leaf litter) are a potential source of natural silica. Silica fertilizer in agriculture is still very necessary, especially in nanosized. Through silica extraction from bamboo leaf litter, it is hoped that it will be able to meet agricultural silica needs and reduce bamboo leaf waste. The aim of this research is to modify the synthesis of silica from ori bamboo leaf litter (Bambusa blumeana) by extracting NaOH and KOH using the hydrothermal sol-gel method to produce nano silica. Nano silica production uses the hydrothermal method because it does not require large costs, is more effective, and has a high level of purity. Synthesis of original bamboo leaf litter silica using the hydrothermal sol-gel method. Bamboo leaf litter ash was analyzed using the XRF test, and silica was analyzed using the SEM-EDX mapping test to determine its morphology and content. The research results showed that synthesis with sodium produced higher levels of bamboo leaf silica compared to potassium. The size of the silica particles obtained is still in the form of micrometers (47–52 µm). Bamboo plants in Indonesia are familiar plants and have not been utilized optimally.

Abstract

The abundance of bagasse waste from sugar cane processing needs special attention apart from being used for direct combustion in boilers. Sugarcane bagasse waste can be further processed by pyrolysis so that it will produce bio-oil, bio-gas and char products which have the potential to be used as fuel or high-value chemicals. Pyrolysis of bagasse was carried out to study the effect of temperature and the ratio of the amount of Ni catalyst on the yield and composition of bio-oil in the form of oxygen to carbon (O/C) ratio, hydrogen to carbon (H/C) ratio, higher heating value (HHV), content of oxygenated compounds and range of aromatic compounds. Pyrolysis of bagasse is carried out in a fixed bed reactor with a heating rate of 10-12 ºC/minute to the desired temperature. Pyrolysis with and without a catalyst was carried out at a temperature range of 300-600 ºC with a variation of Ni catalyst weighing 2.5 grams and 5 grams. Liquid product analysis was tested using GCMS (Gas Chromatography and Mass Spectroscopy) to determine the compound content in the liquid product resulting from pyrolysis of sugarcane bagasse. Bio-oil resulting from pyrolysis of sugarcane bagasse contains several dominant compounds including alcohol, fatty acids, esters, carotenoids and levoglucosan. However, the yield of sugarcane bagasse bio-oil without catalyst was dominated by high levoglucosan, namely 70.52%. Meanwhile, the bio oil resulting from pyrolysis which varied with 2.5 grams and 5 grams of Ni catalyst was dominated by esters, namely 69.07% and 81.68% respectively. These compounds have different chemical properties and applications, and understanding the composition of bio-oil can help in deciding how to use it efficiently.

Abstract

High-quality air is essential for human survival. The present-day has a negative effect on air quality. Air contamination from the harmful compound H2S is an important problem. The primary source of H2S discharges is the oil and gas industry, where it is a by-product of resource harvesting and processing. Further sources of H2S discharges into the atmosphere include mining, waste management, and fossil fuel burning. H2S generates a malodorous scent resembling that of decayed eggs, which can prompt respiratory discomfort and irritation in humans and animals. At elevated concentrations, it may induce toxicity and even fatalities. Biofiltration is one of the latest remarkable technological advances for mitigating this issue. This method employs microorganisms to convert H2S into less harmful compounds. Biofiltration offers the major benefit of low operational expenditure and minimal environmental impact. This paper contributes to our comprehension of the microbial parameters, designs, models, applications and processes that affect biofilter efficiency. Diffusion-based biofiltration models show greater efficacy in design systems. Furthermore, advances in media, including the use of hollow cylindrical particles, have increased the efficiency of biofiltration. Sulfur-oxidizing microorganisms, such as Thiobacillus sp., play a pivotal role in decreasing H2S compounds.  It is crucial to regularly monitor and regulate moisture levels, pH, temperature, and nutrient content to secure optimal and consistent biofiltration performance. The technology's effectiveness and stability heavily depend on precise control of these parameters. Biofiltration technology is hailed as a promising approach to manage H2S compounds, safeguard air quality, and preserve human health and the environment.

Abstract

Cowpeas are a particular kind of legume and contains the second highest protein after soybeans. Cowpea is inadequate because it has antinutritions such as tannins, phytic acid, and trypsin inhibitors. Pretreatment is necessary to lower anti-nutritional elements and increase the nutrition of cowpeas' ability to be digested. This study was done to determine the effect of various pretreatment techniques on enhancing cowpea flour's nutritional qualities and antioxidant potential. A completely randomized design with one factorial and three analytical replications was done. The findings of this study demonstrate that cowpea flour may be made using a variety of pretreatments, including germination, roasting, or its combination. A combination of germination treatment followed by roasting can significantly reduce the phytic acid, tannin, and color content and increase the yield and density of the cowpea flour produced. In addition, the initial treatment with the combination had the highest protein content of 46.88%, the highest total phenol, and the most increased RSA antioxidant activity of 47.00%. The most effective method to produce cowpea flour with the best nutritional properties and antioxidant potential is a combination of germination and roasting processes as a pretreatment.

Abstract

Porang (Amorphophallus oncophyllus) is a tuber plant originating from Indonesia. This plant is less well known compared to other tuber plants. Porang has various important uses, especially in the food and industrial sectors. Indonesia ranks 5th as the largest supplier of porang in the world. Drying porang is an important stage in the post-harvest processing of porang plants. The drying process must be done carefully so as not to damage the quality of the porang. The right drying method, appropriate drying temperature, and humidity control must be considered to achieve optimal drying results. A tray dryer is a drying device that contains shelves to store the material being dried. Drying with this tool uses hot air gusts that are passed over the material being dried. The aim of this research is to determine the effect of drying temperature variations on the moisture content and drying rate of porang using a laboratory-scale tray dryer. Drying is carried out on stick-shaped porang with a thickness of 1 cm and a total weight of 125 grams. The temperature variations in this drying are 50OC, 60OC, and 70OC, with a drying air speed 1 m/s. The research results show that the higher the drying air temperature in the tray dryer, the lower the moisture content in the porang and the faster the drying rate. When the drying air speed and porang thickness are constant, the optimal porang drying temperature is 70OC.

Abstract

This research aims to compare the characteristics of briquettes as an energy source produced from coffee shell waste and cocoa waste. The briquette-making process involves carbonization to produce charcoal as the primary raw material for briquettes. Carbonization time varies, influenced by the type of waste and size of the material. After that, the charcoal is reduced and sifted into fine and coarse powder. Briquette molding uses pressure using a pipe as a mold. The characteristics of briquettes are analyzed through water content, density, burning rate, and ash content. The research results show differences in characteristics between coffee and cocoa waste. The carbonization process affects the time and mass difference of raw materials. Cocoa pod shells require the longest (±35 minutes), while cocoa bean shells require the shortest (±17 minutes). Next, making briquettes involves molding and pressing using a pipe as a mold. The results showed that waste cocoa pod shells and cocoa bean shells produced more briquettes than waste coffee pod shells and coffee bean shells. The moisture content of briquettes from all types of waste meets the standards, but the density of the raw material for coffee husk waste is low, while the briquettes have a high density. The burning rate of briquettes varies, with cocoa bean shell briquettes having the fastest burning rate and producing much smoke. The ash content of cocoa pod husk briquettes exceeds the standard, while cocoa bean husk briquettes have low ash content. The density of the raw material is correlated with the moisture content of the briquettes. The highest burning rate occurs in cocoa bean shell briquettes, influenced by low density and high water content. The ash content of the briquettes meets standards, except for cocoa shell briquettes. This research proves that cocoa and coffee shell waste can be processed into briquettes with different characteristics.

Abstract

The lifestyle of modern society and unhealthy environmental conditions currently cause a decrease in body resistance. This encourages nutritional intake from food that we can obtain quickly and practically without reducing the nutritional value of the food we consume, one of which is processed cereal products.. The aim of this research is to analyze the effect of mixed flour formulations on the physico-chemical and sensory characteristics of cereals using non conventional flour composite raw materials and determine the best cereal formulation based on physico-chemical and sensory characteristics. This research used a completely randomized design with variations in the cereal making formula treatment. The raw materials used are purple sweet potato flour, brown rice flour, corn flour, sorghum flour. Research parameters on cereal products include air content, degree of swelling, % solubility and % air absorption, texture, antioxidants, and sensory tests. The research results show that cereal formulations influence the physico-chemical characteristics and sensory tests. However, the treatment formulation did not have a significant effect on the air solubility index and air absorption index and texture in the sensory test. Based on the sensory test, the formulation preferred by panelists based on texture and taste was F1 (purple sweet potato flour (50%): corn flour (50%)), while based on color it was F2 (purple sweet potato flour (50%): sorghum flour (50%) .

Abstract

Biodegradable bioplastics are the latest solution to the problem of conventional plastics which hurt the environment. Types of biodegradable bioplastics, namely starch-based plastics and cellulose-based plastics, have been developed in many studies. Cellulose can be made into biodegradable bioplastics by adding starch, plasticizers, and strengthening materials with certain variations. This research aims to determine the effect of mixing glycerol plasticizer and the concentration of chitosan on the biodegradable bioplastics produced. The variables observed started from elongation, Young's modulus, density, tensile strength, biodegradability, and water resistance. The best biodegradable bioplastics results for density, tensile strength, and percent elongation values were obtained with variations of 60% glycerol and 3 gram chitosan of 5.62 g / mL, 163.5 KPa and 4.26 KPa; Young's modulus for variations of 20% glycerol and 3-gram chitosan is 45.17 KPa; the water absorption capacity of variations of 20% glycerol and 0.5-gram chitosan is 81.5%; and the bioplastic mass degraded at a variation of 40% glycerol and 3-gram chitosan at 49.21%.
